RENAULT CAN CLIP REPAIR SOLUTION

[tittibritti]

About Cristals it is better to change both with new ones, they are very cheap

Hi all must say a quick thanks for this post as i have been reading it a few times trying to fix my clip which was working fine untill I had a vehicle with bad earth and starting motor problems, this I think has caused some sort of damage to the clip but i can't seem to repair it...... maybe you can help

I'm am getting two red led's (USB & Batt) and the green ISO led,
I have re-installed the software 113 but only the iso driver will install, the can won't

1) have checked soldering joints and gone around with the hot air gun.
2) have swapped over the cypress chips from iso to can.
3) swapped over the crystals from iso to can
4) checked voltage at both cypress chips (3.1v or 3.3v can't remember exactly.)
5) checked voltage at both mc68hc16 ( 5.02v)
6) changed the usb cable

the probe shows up in the clip software but when try to connect I get a error.

have I missed something maybe I can't see the wood for the trees... :-) not sure where to go next!!!!!!

Cheers Paul

Hi
diodes an transistor can be checked with multimeter for short circuit or intreruption (diodes) it worked for me

hi,
did you change the oscilators?

I didn't change oscillator 32.768KHz, but I solved my problem by changing two of the eight transistors FTMM 619 on ISO board.

Regards.

Sorry for the simple question but not sure how to test them I can use a multimeter (voltage, resistance or short circuit checking) but not sure what that component should or shouldn't be doing..... if it's a different number on component then would it operate a different way. I take it were talking about the three legged black item???

identification -diodes - two legged black with one line representing cathode
checking 1. put multimeter on lowest ohm reading (mine is 2k and has a beeper if resistance is less than 200 ohm)
if it beeps on diode it is shorted, you have to unsolder and recheck if still shorted replace.
2. put multimeter on diode range ; put red wire on anode and
black on cathode. if diode is ok you should get 120 - 800 mv reading on scale (120 for sckotky and more for normal diode)
reverse leads on diode terminal you should have no current passing throu the diode. if measurements are uncertain because of other components you can unsolder an check then

transistor -three legged things most of them are mosfets
mosfet has one junction so you can measure one diode between terminals (you have to determine which ones)
if you measure less than 100 mv on diode scale or multimeter
beeps on lowest ohm scale you have to unsolder an remeasure if short circuit still present than replace
bipolar transistor have two diodes you can measure with multimeter on diode scale
I used this to decode transistor types
please watch [ame="http://www.youtube.com/watch?v=b83YUu4Np6A"]this[/ame] and [ame="http://www.youtube.com/watch?v=b0jCUsenNsY"]this[/ame]
you are basicaly looking for short circuit (less than 20 - 40 to 0 ohm between pins ), blown mosfest die in short circuit
blown bipolars have only one junction or none, you have to do trial an error to find out if it is dead bipolar or alive mosfet
there are more transistors of the same type on the board so you can compare measurements.
i had a board (not clip) with shorted electrolitic capacitor and blown diode. i replaced diode twice before finding capacitor, so you should measure caps also
please look after my posts on this thread , maybe i forgot to write something important now
good luck

Hi !
what should I put here in the place of this R5A , because the clip I got don"t have it !

thank"s in advance !

hello,
it is voltage reference 5v (not 7805!), look in attached pdf

I also spend a lot of time with my clip
changed flash and usb chips, but from two new chips (china) one was bad!!!
finally works again

thank"s for replay !

this will do the job ?!

hi
i don't think so
You have to look in pdf I've attached

it is LM4040 - voltage reference

"LM4040
Precision Micropower Shunt Voltage Reference"

and marking R5A -

R2A SOT-23 only First Field:
R4A SOT-23 only R = Reference
R5A SOT-23 only Second Field:
R8A SOT-23 only 2 = 2.500V Voltage Option
R0A SOT-23 only 4 = 4.096V Voltage Option
5 = 5.000V Voltage Option

if you put N-Channel 30-V (D-S) MOSFET from ebay I dont think it will work, and maybe damage other components

ok !

this one !

you need 5 volts, this lm404 2,5v has marking R2A or R2B
I've searched ebay and didn't found 5v in sot23 package

LM4040A50IDBZT - TEXAS INSTRUMENTS - IC, VOLT REF PREC MCROPWR SOT23 | Farnell Rom?nia

this is in farnell romania, you have to search in farnell in your country

Hi !
did any one have the pin layout of can clip ?!
I have one for fix but I don"t have the OBD cable !
another thing !
did I have to feed width 12v to make the software recognize the " sonde " ?!

thank"s

hi
you have to power usb and obd before trying to instal drivers

you should double check this , i don't have clip with me
obd clip
1 11
2 1
3 17
4 14
5 19
6 8
7 2
8 16
9 18
10 7
11 10
12 5
13 4
14 9
15 3
16 6

i used this when my cable was broken I don't know if it is ok for other versions than clip 96

regards
cristi

Yes you need to supply +12V in order that all 4 devices will be shown in device manager.
